LOCOMOTIVE.

Application filed June 3 1913.

comprising a boiler of suiiicient capacity to furnish steam for several independent sets of engine gear, mechanism for simultaneously operating the several sets of engine gear, and means for conserving the use of the power produced by the boiler.

In brief, my improvements comprise an improved boiler construction having a double shell, double shell steam domes, and 1m-' proved means for'collecting and disbursing the dry steam; a mounting for the boiler and the engines, comprising a plurality of trucks, properly articulated; and a com pensating and spring supporting means for the plurality of trucks, the boiler and fire box.

i ug showing the valve and piston arrangement.

1 is a boiler, of sufiiciently large size to supply steam to several sets of engines.

2 is the casing, 3 is the smoke box, and 4: is the fire box (Figs. 1 and 10) the fire door and grate not being shown.

'1 are the stay bolts securing boiler and lire box in spaced relation, (3 are the water legs, 7 is the ash box, (Figs. 2 and 10) bolted to the fire box 4, 8 the grate turner, 9 the dry steam domes (Fig. 1), 10 the dome rings, 11 the dome caps, 19 the dome bases, 13 the dome casings, 14 the dome covers, t'he'construction affording a double casing or jacket for the dry steam within the domes.

15 is a throttle valve to let steam into the valve box 16, 17 is a throttle valve pipe, and 18 an elbow; the pipe 17 and elbow 18 connecting with the main dry steam pipe 24:, 19 is the throttle valve stem fast to the throttle valve cranks 20, mounted between lugs on pipe 17 and operating throttle valve rod 21. The rod 19 is packed with a stulling box or gland 22 where it passes through the rear end of the boiler and is provided with a suitable lever in the cab 23.

The main dry steam pipe 24 communicates with down pipes 25, connecting pipes 26, and supply pipes 27 passing through the arches 28 and the casing pipe 112, whereby steam can be brought to the steam chests 29 of the engines 30.

Pipes 31 convey steam from one to the other side of the boiler and pipes exhaust.

steam through nozzle 33 into the spark dropper pipe 34: above the stack 35, whence it escapes with the sparks and cinders through the catcher 38, the heavier particles falling to the ground.

36 is the nest of boiler tubes or flues, these being larger at the forward end 37 and smaller at the after end, so as to create a stronger draft for a long boiler.

23!) are oil holes or cups to lubricate the parts in' the steam or valve chest 2!). The other and usual oiling means for the several parts of tho locou'lotive arc purposely omitted.

A suction pump 40, without and adjacent the cab, draws water from the tender 41, through pipes 42 into the boiler 1.

a is a waste pipe.

Air pump 43, through pipes 44, furnishes tanks 45 with compressed air for brakes, etc.

Steam dome 46 supplies steam for whistle.

by and supported on frame 52' through swinging clippers 59 holding springs 00.

Post hangers 54 rest on boxings 01 mounted in the spaces 62 between dependlng paired frame posts 52 the sj'iac'esb ing closed be low by plates 03 and theboxings having orifices (it for the wheel. axles. The pony truck has a swinging bolster 05 supporting a center pin and supported on a cross tie 00, being connected thereto by the links 67. 68 is a safety strap, and 69 the truck pedestals resting in boxings 61.

Referring to Fig. 6, 70 are the driving rods, 71, 72 and 73, the three parts of the 4 main rods, 71 the stra )S (stub-ended) holding the brass boxings 5. 7 6 arethe keys securing the boxings and 77 are the 011 cups.

78 are the drivmg wheels (see Fig. 3)

having the usual wrist pins 79 for the brass boxings of the main rods, and 80 for those of the pitman rods, 81 being washers between the rods and 82 being taps to retain the rods on the pins.

83 are the forward running wheels.

84 is the lever for moving the long rod 85 which operatesvertical rods 80 to open and close the steam cocks 87 to let out the exengines.

The rear ends of the engines 30 may be provided with a steam protector 109 (Fig. 11) between the slides 89 which guide the cross heads 90.

91 are the piston rods and 92 are exhaust 1 there being two disks and rods connected to each link for each engine. In the cab is a lever 97 which shifts the long reversing rod 98 and through it raises and lowers the arms 100 mounted on a rocking-cross rod 99 which serves as a fulcrum, the movement of the arms 100 raising and lowering vertical reversing rods 101 connected to the'links 96, thus raising and lowering said links in re sponse tothe movement of the lever 97 in the cab. The movement of the links alters the relative adjustment of the eccentric disks.

102 are two part adjustable link blocks joined by a bolt andmounted in links 96.

The movement of the links 96 operates crank sets of running gear frames for each boiler and each frame has its pair of engines, one on each side. There IS a rod and pitman for the wrist pins for the drive wheels, s0 the link movements (shown in Fig. 6) will run the engines on each side of the boiler.

In Fig. 4 are shown the cross rod to raise or lower the link, so that the linkblock will workthe valve rod to work the valve in-the steam chest so the pressure of the steam will work the piston in its running position.

The boiler rests on a plurality of arches;

each in two parts: each part carrying an engine mechanism for its side of the boiler. The boiler rests on braces carried by several sets of running frames, the frames're'sting on boxings, the boxings on axles, the axles borne by the wheels of the locomotive. haust and thus expedite the starting of the l The exhaust passes through a nozzle spark dropper pipe above the stack to prevent back draft of sparks and cinder's, the sparks and cinders passing between the stack and the.

spark dropper pipe, striking the catcher and dropping to the ground.

There are four eccentric disks and rods for two links for each pair of engines, one engine being on each side, of a frame. There may be two or more frames.

llaving thus described my invention the following is what I claim asnew therein and desire to secure by Letters Patent:

1. In a locomotive, the combination of a.

single boiler mounted on a plurality of wheeled frames or trucks, a plurality of engine mechanisms for propelling each frame or truck, and means for'simultaneously conveying power from the boiler to the engine mechanisms comprising a plurality of steamdomes, piping connecting the steam domes directly each with the other, piping connecting the first mentioned piping with each of the several engine mechanisms, and horizontally extending piping connecting each unit of the second mentioned piping at a point near to each engine mechanism direetly with the piping extending tothe other engine mechanisms.

In a locomotive, a fire box supporting means comprising paired side engine frames, paired axle boxings vertically movable in each of said frames, posts mounted on the boxings, paired lever rocking-arms, each fulcrumed, at an intermediate point, on a post, clippers hung from the outer ends of said rocking-arms, springs supported by the dippers and bearing beneath parts of the frames, paired links carried by the inner ends of the rocking-arms, and. a cross piece supported by the links and adapted to support a fire box.

3. In a locomotive, a fire box supporting means comprising paired side engine frames, paired axle boxings vertically movable in each of said frames, posts mounted on the boxings, paired lever rocking-arms, each fulcrumed, at an intermediate point, on a post, dippers hung from the outer ends of said rocking-mans, springs supported by "the dippers and bearing beneath parts of the frames, and a cross piece supported by the inner ends of the rocking-arms and adapted to support a fire-box.

In testimony whereof I. affix my signature in presence of two witnesses June 2, 1913.
